<h2 class="heading hide-accessible">Summary</h2>

The quality of rock mass has significant impacts on the stability of underground excavations. Rock joints that are filled with soft infill are likely to be the weakest planes in a rock mass, having a dominant influence on its overall shear behaviour. This study aims to examine the asperities degradation and damage patterns during the shearing of infilled rock joints having infill with different moisture content. The study aims to investigate the variation in the damage patterns and associated variation in shear strength that this discontinuities undergo after intense periods of rainfall, particularly relevant in open excavations and tunnel portals. The study involves advanced material strength measurements of rock mass at different scales lead by Dr Heitor in the School of Civil Engineering, and stress characterisations (e.g. photonics) lead by Dr Antony in the School of Chemical and Process Engineering. The outcomes would result improving our understandings in this important subject area, and developing predictive models and tools for assessing the impact of rock mass failures due to harsh environmental loading conditions in UK and rest of the world.

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="http://www.leeds.ac.uk/rsa/prospective_students/apply/I_want_to_apply.html">University&#39;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is Investigations on the mechanics of infilled rock joints using inter-disciplinary approaches as well as&nbsp;<a href="https://eps.leeds.ac.uk/civil-engineering/staff/6674/dr-ana-heitor">Dr Ana Heitor</a>&nbsp;as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.

<h2 class="heading">Funding on offer</h2>

<p>A highly competitive EPSRC Studentship Award offering Academic Fee at Home/EU Fee rate, plus Maintenance of &pound;15,285 per year for 3.5 years.</p> <p>The Award can be used to fund projects that would be co-supervised across (at least) two schools within the Faculty of Engineering and Physical Sciences.</p> <p><strong>Note to EU Candidates:</strong>&nbsp;&nbsp;To be eligible for the full award of fees and maintenance, you must&nbsp;have residency in the UK for 3 or more years prior to your start date.&nbsp;If you do not have 3 years residency in the UK, you may be eligible for a&nbsp;<strong>Fee Only</strong>&nbsp;award.</p> <p>Please note that International applicants are not eligible to apply for this funding.</p>
